A style of low-fidelity design diagraming, used for exploring information architecture and the visual organization of page elements.
Here's an analogy.
When organizing your garage, you might loosely assign areas of the space for certain types of tools or equipment. It’s a quick way to experiment with and visualize how users will experience a product and find the information they’re seeking.
Why does it matter?
Blockframing is a highly effective way to quickly organize and arrange information without needing to create high-fidelity designs. Data arrangement and organization is equally as important as the data itself.
How does it apply?
Blockframing is a helpful step before or during the concept design phase of a digital product.
